Abstract (en)
[origin: US2013248170A1] Methods are described for enhancing acetoclastic methanogenesis in subterranean geologic formations. The methods may include accessing a microorganism consortium in the formation, and assessing the consortium for acetoclastic methanogenic activity. The methods may further include modifying the formation environment based on the consortium assessment to increase methane production from acetoclastic methanogenic pathways used by the consortium. The modifications to the formation environment may include introducing an amendment and/or introducing acetoclastic microorganisms to the formation environment.
